COMBINATION" WATER-HEATER.

Specification of Letters Patent.

Patented Mar. 20, 1917.

Application filed October 1, 1914. Serial lfIo. 864,473.

To all whom it may concern:

Be it known that I, JAMES G. SCOTT, a citizen of the United States,residing at l/Vashington, in the District of Columbia, have inventedcertain new and useful Improvements in Combination lVater-Heaters; and Ido declare the following to be a full, clear, and exact description ofthe invention,

-such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to the letters and figures of reference marked thereon, which form apart of this specification.

This invention relates to water heating devices for dwellings and thelike, and has for its object to provide a novel construction andarrangement of the heater.

With this and other objects in view the invention consists in the novelconstruction of the heaterand particularly in the hot water heatingcoils and in the construction and arrangement of the burners, and in theconstruction and arrangement of the housing for the heating coils.

The invention further consists in certain other novel details ofconstruction and combinations of parts, all of which will be first fullydescribed and afterward specifically pointed out in the appended claims.

Referring to the accompanying drawings Figure 1 is a top plan view ofthe heating apparatus.

Fig. 2 is an enlarged vertical sectional view through one of the heatingcoils, the burners and the coil housing.

Fig. 3 is a bottom plan view of the heater, illustrating'the heatingcoils and their connections, and also the gas or fuel piping.

Like numerals of reference indicate the same parts throughout theseveral figures, in which 1 indicates the heater which may be of anyform, size or construction, preferably of the type of the usual domesticgas stove or range and which may have any suitable number of burnerholes, as for instance four as illustrated in the drawings.

The top 2 of the stove or heater is provided with the usual skeletonopeningjor spiders 3 to receive cooking and culinary vessels, and thehousing 4 (Fig. 2) for the heating coils 5 are arranged under thespiders 3, the said coils 5 being arranged over the burners 6, 7 and 8.

Referring now to the specific construction of the coil housings 4 andparticularly to Fig. 2 it will be'seen that said housing 4 is dividedinto 2 compartments, namely, the outer compartment 9 and the centralcompartment 10, a portion of the coil 5 being arranged in the outercompartment 9 and passing through the wall 11 into the centralcompartment 10, in which latter compartment the coil 5 is preferablyarranged in twoor more layers, the number and size of which layersdepending upon the character of the heater and the purposes for which itis to be .used.

Referring further to Fig. 2 it will be seen that the wall 11 forming thecentral compartment 10 extends vertically to a point above the uppermostlayer 12 of the coil 5 Where it flares abruptly to form the wall 13,which wall joins with the top 2 of the stove or heater.

The purpose of this construction is to accommodate the coil 5 to theaction of the two independent burners 6 and 7. The heat from the burner6 being directed to that portion of the coil 5 within the compartment 9and to the outer sides of that portion of the coil 5 within the centralcompartment 10, the said burner being so located as to prevent anappreciable quantity of heat from passing up through the centralcompartment 10 and to the spider 3 above the same. The wall 11 and theflared wall 13 also prevent the direct heat from the burner 6 passing tothe spider 3. The purpose of the burner 7 which is partitioned from theburner 6 by an annular vertical wall 14 is to supply heat directly tothe central layered portion of the coil 5 and directly to or under thespider 3 of the stove or heater.

The purposes of this construction are to prevent excessive heat directlyto and under the spider 3 when the burner 6 is in operation, it beingdesired to confine the direct heat passing to the spider 3 to that heatfrom the central burner 7.

Referring now toFig. 3 which illustrates the connections to and from theheating coils it will be seen from this figure that the pipe 22 leadingfrom the hot water tank or boiler (not shown) is provided with asuitable connection 17 such as a cross, to which connec tion 17 theouter end 18 of each heating coil is connected. It will beseen that theinner end 19 of each heating coil 5 is suitably connected as at 20 and21 to the pipe 15, which leads to the hot water tank or boiler (notshown).

40 indicates the gas supply pipe leading to the burners 6.

Each of the burners 6 is provided with a pilot burner 8 connected to thegas pipe A3 by means of which the outer burners 6 are lighted to heatthe heating coils. As will appear from Fig. 3 the central burners 7 aresupplied with gas independent of the supply to the outer burners (3, thenumeral 41 indicating the gas supply pipe to the central burners 7 whichpipe is provided with manually operated valves 42 to control the supplyof gas to the central burners 7.

Having thus fully described the invention it is of course apparent thatthe accompanying drawings are diagrammatic and that the arrangement andconstruction of the parts must necessarily be changed or altered to meetvarying conditions, and I therefore consider myself clearly entitled toall such changes and modifications as fall within the limit and scope ofthe appended claims.

What I claim as new and desire to secure by Letters Patent of the UnitedStates is 1. A device of the character described comprising a heatingcoil, the innermost portion of which is formed with one layer over theother, a housing tor said coil partitioned into two compartments andindependent burners for heating said compartments inde pendently.

2. A device of the character described comprising a heating coil, theinner portion of which'is formed in layers one over the other, a housingfor said coil partitioned to provide a central compartment and an outerannular compartment, the central portion of said coil being disposed insaid central.

compartment, the outer portion of said coil being disposed in said outerannular compartment and independent burners for heating saidcompartments.

3. A device of the character described comprising a heating coil, ahousing for the same partitioned into two compartments, the centralportion of said coil being disposed in one compartment, the outerportion of said coil being disposed in the other compartment andindependent burners for heating the said compartments and the coiltherein.

4. A device of the character described comprising a heating coil, ahousing therefor partitioned into two compartments, the central portionof said coil being disposed in one compartment, the outer portion ofsaid coil being disposed in the other com partment, an independentheater under each compartment, means above said housing for supportingcooking utensils, said housing comprising means for preventing excessiveheat from one of the said burners passing to the said means forsupporting the cooking utensils.

5. A device of the character describedcomprising a heating coil, ahousing therefor partitioned into a central compartment and an outerannular compartment, the central portion of said coil being disposed insaid central compartment, the outer portion. of said coil being disposedin said outer compartment, a heater under said central compartment,means for supporting a cooking utensil above said central compartment toreceive heat therethrough from the said burner, an independent burnerunder said outer compartment for heating the portion of the said coiltherein, the said housing in cluding means for preventing excessive heatfrom the last mentioned burner to the said means for supporting acooking utensil.

6. A device of the character described comprising a heating coil, ahousing partitioned into a central compartment and anouter annularcompartment, the central portion of said coil being disposed in the saidcentral compartment, the outer portion of the said coil being disposedin the said outer compartment, a burner under the said centralcompartment, means for supporting a cooking utensil above the saidcentral compartment, an independent burner under the said outercompartment, said housing including a vertical annular wall forming thesaid central compartment, and an outwardly flared wall above the saidouter compartment, said walls being arranged to prevent excessive heatfrom the last mentioned burner from passing to the means for supportinga cooking utensil.

7. A device of the character described i11- cluding a heating coil, ahousing partitioned into two compartments, the central portion ofsaidcoil being disposed in the central compartment, the outer portion ofsaid coil being disposed in the outer compartment, means for heating thetwo compartments independently.

In testimony whereof, I affix vmy signature, in presence of twowitnesses.
